Abstract
A method of temperature stabilizing an optical waveguide (11, 12) having a positive thermal optical path length expansion affixes the optical waveguide to at least two points of a material having a negative thermal expansion and comprises the material of a composite of a resin matrix having embedded therein fibers having a negative thermal expansion coefficient and optionally fibers having a positive thermal expansion coefficient, whereby to provide the negative thermal expansion.
